    •  rapid advances in
      • equipment and
        • speed
        • resolution
          • with multidetector technology
        • ultra-low radiation exposure
          •  100 milliSieverts (mSv) exposure as the threshold for low dose
            • current  clinical coronary CTA
              • 1-10 mSv
              • exams at 10 to 100 times lower exposure
              • comparable to the average annual exposure in the US from natural sources (3 mSv).
      • analytic software. Contemporary CT scanners offer excellent imaging at .
